Globular star clusters form a huge halo around the Milky Way Galaxy. If we resided at the center of our Galaxy, we would see them in every direction. However, we reside not in the center, but more than half way to the edge. We therefore view them in the direction of the galactic center, which we see best in summer. They are almost totally absen ...…
The North Fork Valley of the Gunnison River has built its reputation on riches from the Earth, whether coal deposits to fuel the mining economy, or fertile irrigated land for the valley's productive agriculture. But what might surprise you is the amazing resource found when we raise our awareness up above towards the night sky.…
Earlier this year we lost a space exploration giant. Or better yet, a small robot. On February 13, 2019 we said a final farewell to our good pal, the Mars Opportunity Rover. That day, NASA’s last attempt to reach the rover failed. Its mission finally ended. If it had a burial site, its epitaph may read something like “Opportunity Rover: Roll on ...…
Friday June 21st marks this year’s summer solstice. The word “solstice” comes from the Latin words “sol,” meaning ‘sun,’ and “stitium,” meaning ‘stopped.’ Ancient sky observers noticed that the sun achieved its highest possible position in the sky on this summer day each year.By Jeff Reynolds.
On June 13, 2010 a bright fireball streaked across the sky over Australia. Was this a meteor or an errant piece of space junk burning up in Earth’s atmosphere? Actually, none of the above.

Year 2019 is in full swing and features some eye-catching astronomical events .By Jeff Reynolds.
Here we sit in the middle of January 2019. Yet follow the months back to January of 1805, to find Meriwether Lewis, William Clark, and their crew overwintering at Fort Mandan, in the heart of North Dakota. Like sailors of old who navigated seemingly endless oceans, Lewis and Clark were explorers, gazing across a vast sea of snow-covered plains, ...…
